int arguments

[batousai]

Hi

i am really struggling with something which i think is very basic.

i am trying to write a piece of code that will allow 2 objects to move into 2 different positions

I will show you what the method looks like, then maybe you can tell me where i am going wrong

public void moveToPosition (int a, int b)

{
object1.setPosition(a)
object2.setPosition(b)
}

when i try having just (int a) and applying it to both variables the objects move into the same position, but i just can't figure out how to move them to different positions.

thanks

What's wrong with the code you're showing us? Does it cause bad behavior? Does it not compile?

Also, when posting code, don't highlight it with bold tags, [b] [/b]. Instead use code tags: [code] [/code] so that your code formatting is retained.

hi

first of all i am using something called blueJ which is a training platform

it compiles, but when i try to move the objects in the display i get an error

[Fubarable]

If you get an error, you'd best show it to us. We're terrible at reading minds.

Sorry, i thought you would see something wrong with that method, i've only been learning over the past couple of weeks, so i finding this very difficult

the error is: java.lang.NoSuchMethodError

[Fubarable]

What line causes this error to occur? Is it the two method calls inside of your method? If so, you need to know what the variable type of object1 and object2 are, and only call legal methods for those variables. Again, we're missing information here and can only help us as well as you let us.

java.lang.NoSuchMethodError:
moving.moveToPosition(II)V
in (Workspace:1)


when i use 1 int value in the header it works, but when i use 2 int values, i get this error

I am a little less perceptive than Fubarable... could you please post the whole code segment, that is at least the complete method/class and the complete error message...

That must be a runtime error, because Javac (the compiler) never shows the signatures of methods in their internal form (II)V; it is trying to tell you that no method returning void (V), that takes two int parameters (II) exists. The method you showed us in your OP wasn't actual code which is very confusing. Always show us the actual code that is giving you problems and show the actual error messages as well.

kind regards,
